512 conjugacy classes of subgroups; only the 269 normal subgroups are shown.
This group has 512 conjugacy classes of subgroups — too many to draw. Only its 269 normal subgroups are shown.
Dotted edges: containments with no intermediate normal subgroup — omitted non-normal subgroups may lie between.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 3. #23781691 | C2 | direct (N × H) |
| 4. C2×Dic163⋊C8 | C2 | semidirect |
| 14. Dic163⋊C8 | C22 | semidirect |
| 66. C2×C163 | #424 | semidirect |
| 69. C163 | C2×#424 | semidirect |
| 136. C2 | #23781691 | direct (N × H) |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
